Courting a disaster in battle (9)
I believe the answer is:
agincourt
'battle' is the definition.
(Agincourt is an example)
'courting a disaster' is the wordplay.
'disaster' indicates anagramming the letters.
'courting'+'a'='courtinga'
'courtinga' anagrammed gives 'AGINCOURT'.
'in' acts as a link.
(Other definitions for agincourt that I've seen before include "1415 battle in the Pas-de-Calais" , "where Henry met Constable" , "Battle in Hundred Years' War" , "English-French battle" , "Fourteen fifteen English victory" .)
